Description

A kind of orthodontic bracket

Technical field

The utility model relates to a kind of gear division medicine equipment, and more particularly, it relates to a kind of physiology device that can make collaborative other teeth of indivedual serious dystopy teeth move together.

Background technology

Orthodontic treatment is a subdiscipline that degree of specialization is higher of dental field, is mainly to rescue for tooth, jawbone, facial deformity, by oral cavity, the inner Fixed Orthodontics appliance of installing recovers patient's normal occlusion function gradually. Bracket is the important component part of orthodontic appliance, is mainly adhered on labial teeth, canine tooth, premolar teeth, and orthodontic treatment is by being arranged in the groove of bracket rescuing arch wire, and the Tooth Movement of guiding dislocation is to desirable position.

No matter at present bracket on the market, be locking bracket or common bracket, and an arch wire is all only installed, and makes whole row's tooth only depend on the active force of an arch wire to complete and come into line. Because patient's the state of an illness is varied, especially the teeth arrangement of some patients were is extremely irregular, the distance staggering between tooth is larger, and the degree of crook of arch wire is limited, can not meet once all teeth are drawn, so tend to take secondary to come into line, in the time coming into line the stage for the first time, to staggering, the less tooth of distance once comes into line, after having come into line, separately the tooth of indivedual severe deformities is come into line again, so just directly cause coming into line the situation of excessive cycle, patient's normal life is impacted.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of orthodontic bracket, can realize in the stage that comes into line for the first time and just the tooth of indivedual severe deformities being come into line.

For achieving the above object, the utility model provides following technical scheme:

A kind of orthodontic bracket, comprises supporter groove, and described supporter groove is provided with the archwire slot for holding arch wire and is positioned at the tie wings of archwire slot both sides, on the sidewall of described supporter groove, is provided with via hole along the nearly middle direction far away of archwire slot.

Further, the length of described via hole is less than or equal to the middle direction length near far away of described archwire slot.

Further, described via hole is c-shaped, and its opening two ends are connected with the bottom of tie wings and the sidewall of supporter groove respectively.

Further, one of them tie wings is provided with the draw hook for auxiliary traction.

Further, described via hole is positioned at the jaw side of supporter groove.

Compared with prior art, the utility model has the advantages that: by above technical scheme, in the time coming into line for the first time, just can on whole trouble teeth, bracket be installed, and the relatively little arch wire of bracket of distance that staggers is linked together, then at second arch wire of bracket placement staggering on the larger trouble tooth of distance, the second arch wire is penetrated on the via hole on other bracket simultaneously; Due to second arch wire from the via hole on other bracket than archwire slot more close to, so in the time connecting, need bending degree just less, easily realize.

Brief description of the drawings

Figure 1A, Figure 1B are orthodontic bracket structural representation while being locking bracket;

Fig. 2 A, Fig. 2 B be orthodontic bracket while being locking bracket via hole adopt the schematic diagram of C shape structure;

Fig. 3 A, Fig. 3 B are orthodontic bracket structural representation while being common bracket;

Fig. 4 A, Fig. 4 B be orthodontic bracket while being common bracket via hole adopt the schematic diagram of C shape structure;

Reference numeral: 1, supporter groove, 2, archwire slot, 3, tie wings, 4, draw hook, 5, via hole.

Detailed description of the invention

As shown in Figure 1A, Figure 1B, a kind of orthodontic bracket, comprises supporter groove 1, and supporter groove 1 is provided with the archwire slot 2 for holding arch wire and is positioned at the tie wings 3 of archwire slot 2 both sides, on the sidewall of supporter groove 1, is provided with via hole 5 along the nearly middle direction far away of archwire slot 2. Therefore in the time coming into line for the first time, just can on whole trouble teeth, bracket be installed, and the relatively little arch wire of bracket of distance that staggers is linked together, then at second arch wire of bracket placement staggering on the larger trouble tooth of distance, the second arch wire is penetrated on the via hole 5 on other bracket simultaneously; Due to second arch wire from the via hole 5 on other bracket than archwire slot 2 more close to, so in the time connecting, need bending degree just less, easily realize.

As shown in Fig. 2 A, Fig. 2 B, on the basis of such scheme, the shape of via hole 5 can be arranged to C shape, and its opening two ends are connected with the bottom of tie wings 3 and the sidewall of supporter groove 1 respectively. The benefit arranging is like this that one side can be saved certain material, reduces costs; Can make on the other hand supporter groove 1 there is higher intensity, in the process of traction, via hole 5 has a tie point with tie wings 3 and supporter groove 1 respectively, it is in the time being subject to the pulling of arch wire so, the pulling force being subject to can be delivered on tie wings 3 and supporter groove 1 by two tie points simultaneously, form leg-of-mutton force structure, make whole bracket stressed more even, thereby be difficult for occurring deformation.

In the present embodiment, the length of via hole 5 can be arranged to be less than or equal to the middle direction length closely far away of archwire slot 2, is preferably the middle direction length near far away that is less than archwire slot 2, is conducive to like this reduce the contact-making surface of arch wire and through hole, thereby reduce certain frictional force, be more conducive to the traction to suffering from tooth.

In addition, the operation to bracket when facilitating clinical manipulation, is also provided with the draw hook 4 for dragging supporter groove 1 in a tie wings 3 therein, and like this, medical personnel just can carry out shifting function to bracket very easily with tweezers. What deserves to be explained is, in the time that reality is used, in order to facilitate the operation of draw hook 4, all that draw hook 4 is arranged to towards the gum side of supporter groove 1, therefore,, in order to prevent that via hole 5 is subject to the impact of draw hook 4 in the time wearing arch wire, be preferably arranged on the jaw side of supporter groove 1.

It should be noted that, orthodontic bracket comprises two kinds, and one is locking bracket, and another kind is common bracket, and scheme provided by the utility model is applicable to any one in above-mentioned two kinds. For example, shown in Figure 1A, Figure 1B, Fig. 2 A, Fig. 2 B, be the structure chart of orthodontic bracket while being locking bracket; And be the structure chart of orthodontic bracket while being common bracket shown in Fig. 3 A, Fig. 3 B, Fig. 4 A, Fig. 4 B, concrete principle is identical with Figure 1A-Fig. 2 B, does not repeat them here.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model. It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
